How To Avoid Food Poisoning From Undercooked Beans 7 Steps

Discard the water before cooking.

Several beans need only a relatively short cooking time: red lentils (cook 20-30 minutes, pressure cook 5-7 minutes), black (turtle) beans (boil for 45-60 minutes, pressure cook 15-20 minutes), fava or broad beans (cook for 45-60 minutes, don’t pressure cook), and great northern (cook 45- 60 minutes, pressure cook 4-5 minutes). Some need a bit longer: chickpeas (cook 1. 5 to 2. 5 hours, pressure cook 15-20 minutes), kidney beans (cook 1 to 1. 5 hours, pressure cook for 10 minutes), lima beans (cook 60-90 minutes, don’t use pressure cooker), and pinto beans (cook 1. 5 hours, pressure cook 10 minutes).

Chickpeas also contain much less hemagglutinin than red kidney beans, and lentils have an even smaller amount.
